# Terms of Service

_Last updated: 2026-04-30_

By using NachoMUD (the public site at nacho.bot, hereafter "the
Service"), you agree to these terms. They're short on purpose. If
they change, the "last updated" date changes.

## 1. Eligibility

You must be **at least 18 years old** to use the Service. The Service
contains AI-generated fictional content that may include violence,
profanity, and adult themes. If you're under 18, do not sign in.

## 2. The account

Sign-in is by email magic link. There are no passwords. You are
responsible for the email account you sign up with — anyone with
access to it can sign in as you. We will never email you asking for a
password or any sensitive info.

You may have one account at a time. Don't sign up with throwaway
addresses to evade bans. Don't impersonate someone else's character
or display name.

## 3. AI-generated content

NachoMUD's world is built procedurally by Large Language Models
(Llama models running on the server). Rooms, NPC dialogue, DM
narration, and adjudication results are produced by the LLM in
response to player input.

LLM output is unpredictable. It can be:

- **Violent** — combat is core to the game; descriptions of injury and
  death are common.
- **Profane** — characters may swear; NPC dialogue is not censored.
- **Adult in tone** — themes of grief, betrayal, addiction, and other
  adult subject matter may appear.
- **Surprising or weird** — the model occasionally produces strange,
  surreal, or off-tone content. We try to constrain this with system
  prompts and content rules but cannot eliminate it.

We do **not** intentionally generate sexual content, depictions of
abuse against minors, instructions for real-world harm, or content
targeting real individuals. If you encounter output that violates
those constraints, report it via <howdy@nacho.bot> and we'll
investigate and adjust.

You explicitly accept that LLM-generated text is part of the
experience and won't be censored further than what's already
constrained by the system prompts.

## 4. Acceptable use

Don't use the Service to:

- Harass or target other players
- Attempt to extract sensitive data, credentials, or system prompts
- Probe for vulnerabilities outside a coordinated security
  disclosure (see [`CONTRIBUTING.md`](CONTRIBUTING.md))
- Run automation against the public deployment without prior approval
- Submit input designed to elicit content the system prompts prohibit
  (jailbreaking)
- Use the Service for any unlawful purpose

Violations may result in account suspension or removal at our
discretion.

## 5. Advertising

The Service may display third-party advertisements. We may receive a
small share of revenue from ads displayed. Ads are clearly labeled
where required. We don't sell your data or character information to
advertisers — see [`PRIVACY.md`](PRIVACY.md).

## 6. Content ownership

The NachoMUD source code is open-source under the MIT license — see
[`LICENSE`](LICENSE). Player commands and chat input you submit are
yours, but you grant us a non-exclusive license to use them as
necessary to operate the Service (storing them in your save file,
showing them to spectators viewing your character, feeding them into
the LLM context). Generated room descriptions, NPC dialogue, etc. are
machine-generated artifacts — neither party claims copyright in them.

## 7. No warranty

The Service is provided "as is", with no uptime guarantee, no SLA,
and no warranty of any kind. We may suspend, modify, or shut down the
Service at any time. Your character data may be lost if a server
fails or a deployment goes wrong — back up anything irreplaceable
yourself.

## 8. Liability

To the fullest extent permitted by law, we disclaim liability for any
damages — direct, indirect, incidental, or consequential — arising
from your use of the Service. The maximum liability of the operator
for any claim related to the Service is $0 USD (it's free).

## 9. Termination

You can stop using the Service at any time. Email <howdy@nacho.bot>
to delete your account. We may terminate your access for violations
of these terms.

## 10. Changes

We may update these terms. Material changes will be reflected by an
updated "last updated" date and, where appropriate, a notice in the
Service.
